Solve: 5x-3=11+12x; 17x-3=11; 17x-3+3=11+3= 17x=14; x= 14/17 is this right?
Not quite. In your first step, you aren't doing the same thing to both sides of the equation.
5x-3 = 11+12x
You correctly recognized that you need to isolate the x terms on one side. However, if you subtract 12x from the right, you need to subtract 12x from the left, not add. So:
-7x - 3 = 11
You didn't make any other mistakes after that point. Following the same steps from here should give you the right answer,
Thank you, I see my error.
